Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to fig. 3, the present invention provides an embodiment: the utility model provides a novel bluetooth speaker, includes audio amplifier main part 1, audio amplifier main part 1 includes first lid 2, second lid 3, two medium pitch loudspeaker 4, two loudspeaker 5, two vibrating diaphragms 6 and PCB board 7, first lid 2 forms handle 8, inside cavity formation cavity, two with 3 cooperation installation both sides of second lid two medium pitch loudspeaker 4, two loudspeaker 5, two vibrating diaphragms 6 and PCB board 7 all set up in the cavity, and wherein, two medium pitch loudspeaker 4 and two loudspeaker 5 stretch out on first lid 2, and two vibrating diaphragms 6 stretch out on second lid 3, the inside cavity of handle 8 of both sides, and link up mutually with the cavity. The hollow setting of 8 inside of handles has increased the spatial position of cavity, can make the audio frequency vibrate in the cavity, produces the high quality audio.

Wherein, two mediant loudspeaker 4 and two high english loudspeaker 5 are fixed on first lid 2 through two first casting die 25 and two second casting die 26 respectively, and two vibrating diaphragms 6 are fixed on second lid 3 through two vibrating diaphragm casting die 28, and storage battery 21 passes through battery casting die 27 to be fixed in the cavity, and leaded light post 20 and pilot lamp 17 are connected through shading piece 29.

For a mini-speaker, due to volume limitations, the speaker used cannot be too large, and is generally used with a speaker of 2 inches or less, so that, due to the small aperture of the speaker, the volume of air pushed by the speaker is small each time the speaker vibrates, and the low volume sensation is directly related to the volume of air pushed by the speaker, and thus, the natural defect of the mini-speaker results in the lack of bass. Set up vibrating diaphragm 4 for this, set up the vibrating diaphragm for this in pronunciation main part bottom, when loudspeaker work was sounded, loudspeaker vibration can lead to the air in the box to be compressed and expanded, and under the effect that atmospheric pressure changes, the vibrating diaphragm produced the vibration, promoted the air outside the box, just so can sound. Because the vibrating diaphragm can be designed at the bottom or the rear part of the sound box, the vibrating area of the vibrating diaphragm can be larger. Therefore, the volume of the pushing air is increased, the bass volume is greatly improved, meanwhile, the caliber of the passive vibrating diaphragm is increased, the frequency of a resonant product of the passive vibrating diaphragm can be reduced, and the sound box can obtain better bass diving depth when sounding. Through setting up two vibrating diaphragms 6, rely on great vibrating diaphragm 6, even if use little loudspeaker, mini audio amplifier also can obtain better bass effect.

The medium-pitch loudspeaker 4 is matched to play medium-pitch, the high-pitch loudspeaker 5 plays high-pitch, and the medium, high and low pitches of music can be displayed, so that the music playing quality is improved.
